Temporarily having the body of a woman would let me learn the answers to some interesting prurient questions, but if I had my choice of temporary body then I would definitely pick to be a bird and experience what flying feels like.
(I don't identify as much with my body as some other people apparently do. It's the only flesh I have ever been incarnated in so it has a lot of sentimental value but it fundamentally isn't me. It's a thing that I have.)
